==== Bronstein delay ====
The '''Bronstein delay''' (named after [[David Bronstein]], its inventor), like increment, adds a fixed amount of time after each move, but no more than the amount of time spent to make the move. For example, if the delay is ten seconds and a player uses ten or more seconds for a move, ten seconds are added after they complete their move. If the player uses five seconds, only those five seconds are returned to the clock. This ensures that the main time left on the clock can never increase even if a player makes fast moves. As with increment, under FIDE and US Chess rules, the delay time is applied to the first move.

Bronstein delay and Simple delay are very similar, but not equal. In Bronstein delay the amount of time is added ''after'' the move has been made; this distinction may be crucial when a player is running out of time.<ref>{{Cite web |title=Simple Delay Setting Replaces Bronstein in US Clock Rules |url=http://www.chicagopoint.com/clock2013.html |access-date=2024-01-01 |website=www.chicagopoint.com |quote=For the most part, both methods are substantially the same in terms of the amount of time players get and consume. At the end of the move, after the clock is hit, the remaining reserve time will be identical with Bronstein and Simple Delay. The difference is in the time available to complete the current move and becomes apparent when the reserve time runs down close to zero. Because Bronstein does not award the per-move allotment until after the move has been completed, you can run out of time and lose the match before getting the per-move allotment for the current move.}}</ref> The advantage of the Bronstein delay is that the player can easily see how much time is remaining without mentally adding the delay to the main clock. The advantage of the simple delay is that the player can always tell whether the delay time or the main time is counting down. The simple delay is the form of delay most often used in the United States, while the Bronstein delay is more often used in most other countries.
